Software · Infrastructure · Security
I design and build web platforms for companies and public institutions, implement and tidy up IT infrastructure, and help organisations meet the requirements of NIS2, the Polish KSC Act and KRI. One partner from the first line of code to the security audit.

projects and implementations delivered
Software, infrastructure and security overlap in every project. That is why I handle them together.
Web platforms for companies and the public sector, e-commerce and B2B systems, and ERP integrations.
Complex migrations without downtime, standby data centres and fault-tolerant systems, delivered to plan and finished with handover documentation.
Compliance audits, penetration testing, SIEM/SOC monitoring and incident resilience, in line with NIS2 and the KSC Act.
Public offices, local government units and courts. Systems compliant with KRI, preparation for NIS2 and the KSC Act.
ERP integrations, B2B portals for distributors, automated document and invoice workflows.
Online shops and sales platforms connected to the warehouse, payments and logistics.
Custom applications, secure remote work, backups and infrastructure care.
Wojciech Szymała, owner of NEST
I have worked in IT for 27 years and have run NEST since 2014. I have been programming in Python for 15 years, mostly in Django. I build platforms for public institutions and companies, including ABI Online, which is used by courts and public offices across Poland.
Alongside software, I work on infrastructure and security: Active Directory and Windows Server, virtualisation (Hyper-V, Proxmox VE, VMware), Veeam backups and FortiGate-based networks. I have co-authored information security procedures, I carry out KRI audits and penetration tests, and I prepare organisations for NIS2 and the KSC Act.
For clients, this means one person who understands the whole system: the code, the servers it runs on and the security around them.
Case studies and expertise
SaaS platform
A platform for managing information security and personal data protection, built for data controllers and data protection officers. It is used by courts, public offices and private companies across Poland.
B2B and ERP integration
A complete sales platform for the trade partners of an electrical equipment manufacturer, with two-way integration with the ERP system.
Live migration
Migration between virtualisation platforms to a Hyper-V cluster with Storage Spaces Direct, consolidation of several domains into one new AD forest while keeping SID History and permissions, and switching systems over in stages while users keep working.
Ransomware response
Isolating infected segments, finding the entry vector, recovering the Active Directory forest in a clean room, restoring data from immutable and air-gapped backups, and bringing systems back in order of their RTO and RPO priorities.
Disaster recovery
Continuous replication of virtual machines to a second site, automated failover and failback plans, stretched networks between sites, and regular recovery tests of the whole organisation in an isolated network, without affecting production.
High availability
Windows Server failover clusters, SQL Server Always On availability groups, application load balancing and redundant links. Losing one node does not stop the ERP or line-of-business systems.
I get to know the systems, the people and the requirements, and write down what works, what is a risk and what needs to change.
A specific offer with a schedule and costs, also ready for public procurement procedures.
I work in stages, in maintenance windows and with a rollback plan, so the organisation keeps running without downtime.
An acceptance report, handover documentation and further support in the model you choose.
